Abstract
Na2Bi4IIIBiVAuO11 was prepared by hydrothermal synthesis under 3 kbars oxygen pressure. Its structure was solved from single crystal X-ray d iffraction data. The space group is P4/mbm with a = 12.193(1), c = 3.8 643(3), and Z = 2. The structure consists of square-planar AuO4 groups and chains of comer sharing BiVO6 octahedra linked together by BiIIIO 7 polyhedra. The structural arrangement is topologically related to th e tetragonal tungsten bronze structure. Na2Bi4IIIBiVAuO11 is electrica lly insulating and forms transparent red crystals.
